To all whom it may concern:

Be it known that I, DANIEL S. BAIRD, of the city of Hamilton, in the county of entworth, Province of Ontario, Canada, a subject of the King of Great Britain, havcinvented certain new and useful Improvements in Magazine-Wrapping Machines, of which the following is a specification.

This invention relates to magazine wrapping machines of the type employing rtatable forks which grasp the magazine near the forward edges of its ends, and roll it up with a sheet of paper having a gummed edge. In such machines it is necessary to withdraw the magazines one-by-one from a table whateverthe thickness of themagazine may be. V .I attain my object by'means of the constructions hereinafter fully described and illustrated in the accompanying drawings in which Fig. 1 is a plan feeding mechanism;

2 a side elevation of the same;

-Fig. 4 a similar view of another part of this mechanism; I

Fig. 5 adetail. partly in elevation and partly in section of the feed rollers;

- Fig. 6 a perspective detail illustrating portion of the magazine lifting niecl'ianism; and

7 a detail, partly in section. of'one of the feed wheels and its suppor ing and driving mechanism.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

1 is the frame of the machine suitably shaped to support the different parts. On this frame is supported a table 2, over which the magazines are to be fed to the wrapping means such as hereinafter referred to.

Behind this table is supported a feeding.

trough 3 which is open at the top, and is preferably inclined to facilitate the feeding of the magazines to the forward end. The front board t of the trough is preferably tangential to the periphery of the lower feed roller which is suitably journ alled on the frame 1. lVith this roller co-operates the upper feed roller 6 which is mounted to rise and fall. In the preferred construction this roller is carried by the arms 7 which are journalled on the shaft 8 journalled in the frame of the machine. erably positioned sothat its axis is above the axis of the roller 6, when the latter is in engagement with the upper surface of a comparatively thin magazine. The purpose of this will hereinafter appear.

The fecdroller 6 isa driven roller, and to effect its driving I provide the following mechanism. The center of the ro ler is of reduced diameter and a sprocket wheel 9 is secured thereto, which sprocket wheel is driven, by means of a sprocket chain, from the sprocket wheel 10 on the shaft 8. On the shaft 8 is also secured asprocket wheel 11, driven by a suitable sprocket chain from the sprocket wheel 12 on the main shaft 13. A train ofgearing 14 serves to drive the lower feed roller 5from the shaft 8. The

diameters of the two feed rollers are so pro- 9 portioned that the periphery of the upper feed rol tra els slightly faster than the periphery of the lower feed roller. The pur pose of this is to overcome any tendency of the magazines to curl upwardly, instead of ly ng fiat, as they are pushed along the table 2.

I have sometimes found that magazines of different thickness require different ratios o speed between the surfaces of the two rol ers. I the efore provide see"es 15 of di ferent external diameters wh ich'a e adapted to he sipped over the ends'of the roller and which form the magazine engaging parts the eof.

The magazine engaging parts of the roller 6 are provided with the aline'd notches 16 as indicated particularly in Fig. 5. The back of the magazine when the latter is lifted. as hereinafter described, partly enters the notch or notches, one edge of which forms a sharp shoulder which engages the upper surface of the magazine and ensures a positive bite. so that the magazine starts on its forward movement the il'istauce it is contacted This shaft is prefllO by the two rollers. I thus overcome the tendency to slip, which is the objection to the use of plain rollers, since it is imperative that each magazine is fed forward so that its back, which is the leading edge, just reaches a predetermined position for engagement by the wrapping mechanism. I further found that if the upper feed roller were free to rise and fall, without limitation of its downward movement, that a thick magazine will be fed forward further than a thin one, owing to the fact that the upper roller will remain in contact with it for a longer period than it would with a thin magazine. I therefore provide means whereby the downward movement of the upper feed roller may be limited. For this purpose I provide the screws 17, threaded into the frame of the machine, and on which the reduced ends 18 of the feed roller are adapted to rest. By adjusting these screws the time within which the upper feed roller is in contact with the magazine may be regulated. In producing the desired result, the specific arrangement of the mounting of the upper feed roller assists, since its movement is rearwardly as well as downwardly, from which it results that its position when feeding athick magazine is further to the rear than when feeding a thin magazine, and a thick magazine therefore passes from engagement with it sooner than woud otherwise be the case.

In case the weight of the upper feed roller is not sufficient for effective feeding I pro vide a spring 19 which is secured to the frame and bears on the reduced center of the roller. The magazines are lifted for en gagement with the feed rollers by the following mechanism. Disks 20 are slidably and revolubly mounted on the reduced ends 21 of the lower feed roller 5, which disks carry sharply pointed fingers 22 adapted to enter between the leaves of a magazine, as indicated particularly in Fig. 6. Each finger is preferably formed of one or more very thin pieces of steel set olosetogether, so as to engage between the leaves of a magazine in different positions to ensure the mag azine being lifted without being turned. The l fting is effected by moving the disks toward the i'nagazine to engage the fingers as s own in dotted lines in Fig. 6. then rotating the disks through an arc of about 9 then sliding the disks outwardly to disengage the fingers and finallv rotating the disks in the reverse direction to return the fingers to their initial position. These movements are e fected bv t e following mechanism. The s aft 2?) is driven by a train of gearing'24e f om the main shaft 13. Th s shaft carries two pairs of cams 25. 26. Each cam 25 is a f ce cam with high and low portions adapted to engage a shifter lever 27 fulcrumed i unedi te ts ends on the frame of the machine, and forked at its upper end to engage a groove 28 formed in each disk 20. The other cam 26 of each pair is a rim cam provided with high and low portions adapted to engage a projection 29 on a slide rod 30,

provided with a yoke 31, whereby it may responding disk 20. The pinions 34: are of sufficient length to permit them to be axially moved with their disks 20 and yet be engaged by the racks 33. The shaft is so driven. and the cams so figured as to produce the sequence of movements of the disks 20 as hereinbefore referred to.

I have found that a simple inclined feed trough does not always feed forward the magazines to the front end of- "he trough with such certainty as to ensure them being properly engaged by the lifting fingers and fed between the feed rollers. I therefore find it desirable to provide means whereby the magazines, no matter how many may be lying in the trough, will be properly fed forward and firmly pressed against the front 4-. of the feed trough and the lower feed roller 5. For this purpose I provide an endless travelling band or tape 35 at the bottom of the trough. This is mounted on rollers 36 in a manner common in the printing art. Vihile the movement of the magazines is intermittent, this tape may be constantly driven as it slides readilv by the magazines. To effect its driving, I therefore provide on the forward roller 36 a sprocket wheel 37 driven by a suitable sprocketchain from the sprocket 38 on the main shaft 12. The magazines are placed in the trough with their backs uppermost, and it is therefore necessary that their backs should be firmly pressed against the front a of the feedtrough and the lower feed roll. For-this purpose I provide at each side a feed wheel 39. These wheels are resiliently pressed against the magazine and are frictionally driven so that the drive slips at such times as the magazines are not able to move in the trough. The construction and arrangement of these feeding wheels and their driving 1 mechanism is best seen on reference to Figures 1. 2 and 7 of the drawings.

A bracket 40 is secured to the side of the feeding trougl'i at each side of the machine. In this bracket is mounted a sliding bearing 41. through which passes a spindle 42 to which the feed wheel is secured. In the reccss in the bracket is positioned a coil spring 43 which bears against the bearing d1. Threaded through the bracket is an adjusting screw 44;, by means of which the tension of the spring 43 may be adjusted. Slots 45 are provided in the bracket to provide the necessary play for the spindle L2. The spindle a2 is coupled, by means of auniversal lbl) joint 46, with a spindle at? which passes through a yoke-shaped bracket 48. On this spindle 47 is secured a fixed collar 49. Journalled in the upper part of the bracket 48, and a loose collar 50. Between the jaws of the bracket a pulley 51 is positioned which is loose on the spindle 47. Suitable friction washers 52 are positioned between the pulley and the collars 49 and 50. On the lower end of the spindle 47 is positioned a coil spring 53 which bears against the loose collar 50 and against adjusting nuts 54 threaded on the end of the spindle. By means of these adjusting nuts the spring may be tensioned to give the pulley 51 a frictional driving connection with the spindle. By suitable adjustment the driving effect of the feed wheels 39 on the magazines may be regulated as required.

The feed wheels 39 may be constructed in any suitable manner to grip the ends of the magazines, but I prefer to provide them with slight projections 55, which positively grip the leaves of the magazine. This arrangement gives satisfactory results.

To prevent the magazine next the front lifting with the front er leading magazine as the latter is lifted for engagement with the feed rollers, I provide the finger 56, secured to the frame of the machine, and extending down behind the feed rollers to a position where it is engaged by the magazine as the latter is lifted by the fingers 22.
